The other zaurus devices are interesting for me as I know the platform, they have qemu emulation, there are set of devices which are similar but also have differences and there were one of the original targets for OpenEmbedded and Yocto Project. I did quite a bit of work to get one kernel which could run on multiple devices, as best you could at the time! I'd actually forgotten about the qemu emulation. There is a need for better automated testing around DT in OE/YP and this is making me wonder about a few potential ideas. Is there any conversion to DT you can easily point at as an example of the kinds of changes needed? Cheers, Richard
